[0048] Please refer to Figure 1 ~ Figure 3 and Figure 5 , the present embodiment provides a construction platform for aerial work, which is substantially the same as the construction platform for aerial work in the first embodiment, the difference between the two is that in the construction platform for aerial work in this embodiment, the supporting plate 32 includes a plurality of strips Straight board 321; a plurality of straight boards 321 are arranged side by side.

[0049] Please refer to Figure 5 , the above-mentioned strip-shaped straight plate 321 is provided with an anti-slip texture 322 on one side away from the cross bar 31 .

[0050] In the above-mentioned embodiment, 1. The supporting plate 32 is designed as a structure in which a plurality of strip-shaped straight plates 321 are assembled side by side, which is also beneficial for putting the supporting plate 32 into and taking out from the manhole 5 in parts. 2. Due to working at heights, the anti-skid lin...

[0052] This embodiment provides a method for building a box girder 4 bridge using the above-mentioned high-altitude operation construction platform, including the following steps:

[0053] Step 1: welding a cross-connected steel plate 1 between any two adjacent box girders 4;

[0054] Step 2: Construction personnel enter above the bracket 3 through the manhole 5, and weld and fix any two adjacent box girders 4 through the barrier steel plate 2.

[0055] The construction method of the box girder 4 bridge in this embodiment: the above-mentioned high-altitude operation construction platform is used to build the box girder 4 bridge, which can provide a stable and easy-to-build construction platform without affecting the normal traffic under the bridge. Improve the efficiency of bridge construction.

[0056] Further, after the above step 1, the bracket 3 is placed under the horizontal steel plate 1 through the manhole 5 , and the bracket 3 is installed between the two barrier stee...

Abstract

The invention discloses an aloft construction platform, and relates to the technical field of building construction. The aloft construction platform comprises transversely-connected steel plates, at least two partition steel plates and at least one bracket. The transverse-connected steel plates are each in a long strip shape. The partition steel plates are sequentially arranged on the lower side faces of the transversely-connected steel plates in the length direction of the transversely-connected steel plates. Each partition steel plate extends in the width direction of the transversely-connected steel plates. Each bracket is arranged between any two adjacent partition steel plates. The brackets are opposite to the transversely-connected steel plates. A manhole is formed in the position, between any two adjacent partition steel plates, of each transversely-connected steel plate. According to the aloft construction platform, the rigid hanging is formed through the brackets erected between every two adjacent partition steel plates, and the effect of being high in platform stability without affecting the traffic below the platform is realized on the aloft operation platform. On the basis, the invention further provides a box girder bridge constructing method.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to an aerial work construction platform and a method for building a box girder bridge. Background technique [0002] There are generally three types of existing bridge aerial work construction platforms, which are scaffolding platforms, hanging basket platforms and elevator platforms. [0003] The technical scheme of the scaffolding platform is: use steel pipes and fasteners, the fasteners include pan buckles or bowl buckles, use fasteners to connect the steel pipes horizontally and vertically to form a frame, and erect them on the top after reaching the required construction height platform. Its disadvantages are that there are many materials, it takes up a lot of space, it affects the traffic under the platform, and it takes a long time to build. [0004] The technical solution of the hanging basket platform is to make a hanging basket that can meet the constructio...
